MessageSendFailure: Message send failure for update

So I am trying to load a preview for a SwiftUI view, and it always fails with this error:

MessageSendFailure: Message send failure for update

==================================

|  RemoteHumanReadableError: The operation couldn’t be completed. XPC error received on message reply handler
|  
|  BSServiceConnectionErrorDomain (3):
|  ==NSLocalizedFailureReason: XPC error received on message reply handler
|  ==BSErrorCodeDescription: OperationFailed

What does this mean and how can I fix it? The previews on my other views are working fine.

Here's the view in question:

import SwiftUI

@available(iOS 15.0, *)

struct EventEntryView: View {

    @Environment(\.dismiss) var dismiss
    let keyResult: KeyResult
    @State var text: String = ""

    @FocusState var textIsFocused: Bool
    @State var completesKeyResult: Bool = false

    var body: some View {
        VStack {
            Button("Cancel") {
                dismiss()
            }
            Text("Key Result: \(keyResult.text)")
                .padding()
            Toggle("Goal is Reached?", isOn:$completesKeyResult)
                .padding()
            TextField(
                "Event note",
                text: $text
            )
            .focused($textIsFocused)
            .onSubmit {
                print("Note: \(text)")
            }
            .padding()
            Button("Record Event") {
                print("Recording: \(text) goal is reached? \(completesKeyResult)")
            }
            .padding()
        }
    }
}

struct EventEntryView_Previews: PreviewProvider {
    static var previews: some View {
        if #available(iOS 15.0, *) {
            EventEntryView(keyResult: KeyResult.default)
        } else {
            Text("preview")
        }
    }

}

This view also works when it's included in other views for preview, it's only not working for this preview.
